Chemical herders may be used to sequester and thicken surface oil slicks to increase the time window for performing in situ burning of spilled oil on the sea surface. For herder use to be an environmentally safe oil spill response option, information regarding their potential ecotoxicity both alone...

The use of cleaner fish is an environmentally-friendly approach to combat the salmon louse, threatening commercial salmon farming. Dynamic Energy Budget (DEB) modelling helps understand the bioenergetics of early life stages of the cleaner fish, and can thereby aid optimisation of their culturing...

Edible jellyfish are a traditional Southeast Asian food, usually prepared as a rehydrated product using a salt and alum mixture, whereas they are uncommon in Western Countries and considered as a novel food in Europe. Here, a recently developed, new approach for jellyfish processing and...

Approximately one-third of food produced is lost or wasted (FAO, 2022), and the current food system is a major user of energy, natural resources, and accounts for nearly one-third of global GHG emissions (Crippa et al., 2021). Refrigeration plays a vital role in mitigating losses of perishable food...

This paper proposes a new trawl net model tailor-made for simulation of trawl board and pipeline pull-over interaction. The trawl net is connected to the trawl board by a steel rope referred to as the sweepline. It is crucial that the correct tension level is simulated for the sweepline during the...

In 2020, a modeling practice was presented to perform numerical simulation of waves, where waves generated by a numerical wave tank (NWT) were used as input to a CFD simulation. This paper presents an extension of those practices in the context of wave impact on a gravity-based structure (GBS). It...

While highly successful in terms of profitable seafood production, salmon (Salmo salar) aquaculture may also be a source of potential negative environmental externalities. In an attempt to address these challenges through supporting the development of new technology, the Norwegian government has...

A key driver to offering smart services is an infrastructure of Cyber-Physical systems (CPS)s. By definition, CPSs are intertwined physical and computational components that integrate physical behaviour with computation. The reason is to autonomously execute a task or a set of tasks providing a...

Dynamic positioning is an important control feature for an underwater remotely operated vehicle. This paper presents a nonlinear dynamic positioning controller suited for application to vehicles with model uncertainties, operating in environments with unpredictable disturbances, such as an...

A systematic study of the hydrodynamic coefficients for simplified subsea modules has been performed, to support the estimation of the coefficients needed for planning of subsea installation operations. The coefficients are assessed for a nearly two-dimensional test setup. The tests are performed as...

Protecting the remaining wild salmon stock in Norway is of utmost importance and requires that farmed salmon cannot escape from aquaculture sites. As holes in net-cages are responsible for a large fraction of the escaped salmon the industry has to perform frequent inspections of the fish cage...

Plankton distributions are remarkably ‘patchy’ in the ocean. In this study, we investigated the contrasting phytoplankton-zooplankton distributions in relation to wind mixing events in waters around a biodiversity-rich island (Runde) located off the western coast of Norway. We used adaptive sampling...

This paper introduces the fish feed production routing problem (FFPRP) faced by Norwegian salmon feed producers. The FFPRP is comprised of a production scheduling problem and a rich vehicle routing problem (VRP) and thus denotes a variant of the integrated production scheduling and vehicle routing...

A standardized bench-scale weathering and dispersibility study has been conducted on Breidablikk crude oil at 5 and 13 °C. The dispersibility testing on Breidablikk was included to estimate the viscosity limits and time window for dispersant use. The laboratory data were used as input to the SINTEF...

Based on the initial tests carried out in 2013 we carried out a follow up test at sea that evaluated the performance of the Semi-Circular Spreading Gear (SCSG) based on underwater video recordings, information collected from underwater acoustic sensors and catch comparison analysis between a...
